Means for Solving the Problem

According to a first aspect of the present invention, in a vehicle door frame structure wherein an upright-pillar sash member elongated in the vertical direction of a vehicle door and an upper sash member, which is formed as a separate member from the upright-pillar sash member and forms an upper edge of the vehicle door, are joined together at an upper end of the upright-pillar sash member, the present invention is characterized in that an end portion of the upper sash member on the upright-pillar sash member side is linear in shape, and that at the linear end portion the upper sash member includes an designed portion positioned outside of the vehicle door, and an inner frame portion which is positioned closer to the inside of the vehicle than the designed portion and shorter in length than the designed portion. The upright-pillar sash member is provided at an upper end thereof with a superposed contact portion which is superposed on an end of the inner frame portion of the upper sash member in the direction of the thickness of the vehicle door, the superposed contact portion and the inner frame portion being joined together while being superposed on each other.

As a more specific embodiment, it is desirable for the superposed contact portion of the upright-pillar sash member to have a cup-shaped cross sectional shape so that an inner surface of the superposed contact portion is superposed on the inner frame portion. In this case, it is desirable that a sectional-shape-reduced portion on which the superposed contact portion that has the cup-shaped cross sectional shape is superposed be formed at an end of the inner frame portion of the upper sash member.

Alternatively, it is possible that the inner frame portion of the upper sash member be formed into a hollow tube and that the superposed contact portion of the upright-pillar sash member include a superposed contact insertion portion which is inserted into the tubular inner frame portion to be superposed thereon.

It is desirable for the upright-pillar sash member to include an arc-shaped bent portion at an upper end of a linear portion of the upright-pillar sash member which extends along a center pillar, the arc-shaped bent portion being curved toward the linear end portion of the upper sash member, and for the superposed contact portion to be formed on the arc-shaped bent portion.

This invention with the second feature, is located on external side of the upper sash section in the doorframe structure of the vehicle which possesses with the column setting up sash section which extends to door top and bottom direction and the upper sash section which forms the door rising wood, external side is located on external side of the upper side design component and the column setting up sash section which possess the design section which faces external side possesses the design section which faces, from the upper side design component to be locked by the respective interior side of the column setting up side design component and the upper side design component and the column setting up side design component which consist of another component, the upper sash section with it extends to the both of the column setting up sash section and it features that it possesses the interior side frame component which forms the interior side frame section which is continued.

Because form of the interior side frame component in the boundary section vicinity of the upper sash section and the column setting up sash section when it tries to connect the upper side frame section which parallels to the upper side design component and the column setting up side frame section which parallels to the column setting up side design component in the corner bend of circular arc condition, to produce can guarantee also strength relatively easily it is desirable.

In the upper side design component and the column setting upside design component extending facilities it is done in the frame section and abbreviation and the balance to which respectively, the interior side frame component corresponds is superimposed to the said frame section and it is desirable to be able to provide the being superimposed fixed surface which is locked. In the area of the corner bend of the interior side frame component, not to provide this being superimposed fixed surface in the upper side design component and the column setting up side design component, to prevent the interference of the corner bend it should have tried.

In addition, although, it parallels to the corner bend of the interior side frame component in the column setting up side design component and it forms the top back face which is located on top of the said corner bend and the cover and the said cover which close between the column setting up side design component without the opening extending facilities points to the upper side design component to the position where it is piled up with this top back face, making the structure where the top back face of the column setting up side design component is locked to the design section rear of the upper side design component is desirable.

The mutual fixed part of the upper side design component and the interior side frame component is locked repeating to vehicle top and bottom direction, as for the mutual fixed part of the column setting up side design component and the interior side frame component repeating to vehicle front and back direction, it is desirable to be fixed. This way by the fact that it locks, it is possible to raise the rigidity for the power which sucks out the glass window which is supported in the doorframe to external side.

As for the interior side frame component, you can close interior side and it possesses the open frame section which forms the imperfect tubular section which was opened on external side, when installing the upper side design component and the column setting up side design component the interior side frame component, it is desirable to try to be able to close the open part of this open frame section. Because of this, because the fixed part of each design component and the interior side frame component forms the portion of the tubular frame body, it is possible to guarantee strength with the configuration which is not wasteful.

Directing to the periphery side of the doorframe, the weather-strip retention groove of the uniform section which is opened extends to the both of the upper sash section and the column setting up sash section in the interior side frame component and continues and it is desirable to be formed.

Joining union of the interior side frame component, the upper side design component and the column setting up side design component, has had the weather-strip retention groove which it fits keeps glass run retention groove and weather-strip which it fits keeps the glass run, in order the fixed part of the interior side frame component and the upper side design component, the fixed part of the interior side frame component and the column setting up side design component to be covered respectively, glass run and weather-strip at least by on the one hand, when it constitutes, with respect to appearance it is desirable.

Advantageous Effects of the Invention

According to the present invention, the upper sash member and the upright-pillar sash member can be joined together easily and securely without the need for advanced accuracy control because the upper sash member and the upright-pillar sash member are superposed on each other in the direction of the thickness of the vehicle door in a frame portion positioned closer to the inside of the vehicle than the designed portion.

In addition because the frame section of interior side is formed due to the interior side frame component of one structure where this invention according to another feature, extends to the both of the upper sash section and the column setting up sash section and continues, it is not necessary to connect the interior side frame section in the boundary part of the upper sash section and the column setting up sash section, it is possible to improve productivity substantially. And, the interior side frame component which just is the structure which does not possess the connecting part contributes to also the strength improvement of the doorframe.

In addition, is another body from the interior side frame component concerning the upper side design component and the column setting up side design component which are located on external side, as for rigid guaranty as a frame because it is possible, to make the interior side frame component bear, design degree of freedom of the design section improves. For example, like claim 4 the upper side design component is extended to the position where it is piled up to the upper part of the column setting up side design component, the top back face of the column setting up side design component by the fact that it locks on rear side of the design section of the upper side design component, joint is not expressed to the respective design public aspect of the upper side design component and the column setting up side design component and sees and prospering becomes good. In addition, the structure which locks the top back face of the column setting up side design component on design section rear side of the upper side design component precision management is easy, it is possible to assure also the improvement of productivity.

BEST MODE FOR EXECUTING THE INVENTION First Embodiment

FIGS. 1 through 14 show a first embodiment of a vehicle door frame structure according to the present invention.

A motor-vehicle side door 10 shown in FIG. 1 is provided with a door panel 11, an upper sash (upper sash member) 12 that extends along a door opening of a roof panel 50 (shown by an imaginary line in FIG. 2) of a vehicle body, and a side sash (upright-pillar sash member) 13 that extends vertically along a center pillar 51 (shown by an imaginary line in FIG. 3) of the vehicle body from rear of the door panel 11. The door 10 of the present embodiment is a front seat door, and the forward/rearward direction which will be mentioned in the following descriptions designates a direction determined with reference to the front seat door 10. However, the present invention is not limited to the front seat door and can also be applied to a rear seat door or other doors.

As shown in FIG. 2, the upper sash 12 is provided with a glass-run retaining part (retaining channel) 20 in which a glass run 52 is fitted to be retained thereby, and a weather strip retaining part (retaining channel) 21 which is positioned behind the glass-run retaining part 20 to retain a lip 53 a of the weather strip 53, and a flange-shaped designed portion 22 which faces toward the outside of the vehicle is formed on sides of the glass-run retaining part 20 and the weather strip retaining part 21. A connecting arm portion 23 extends from the glass-run retaining part 20 and the weather strip retaining part 21 toward the inside of the vehicle, away from the designed portion 22, and a main frame portion (inner frame portion) 24 having a polygonal-tubular (sac-shaped) hollow sectional shape is formed on an end of the connecting arm portion 23. A hollow sealing portion 53 b of the weather strip 53 is supported by the connecting arm portion 23 thereon using a clip 54. The glass run 52 and the weather strip 53 (the lip portion 53 a and the hollow sealing portion 53 b) are each made of an elastic material such as rubber. The glass run 52 elastically holds the upper edge of a window pane 58 (shown by an imaginary line in FIGS. 2 and 3) when the window pane 58 is raised. When the door 10 is in a closed state, the lip portion 53 a and the hollow sealing portion 53 b of the weather strip 53 are in contact with the roof panel 50 and are elastically deformed to prevent water droplets from entering inside the vehicle.

As shown in FIG. 3, the side sash 13 is composed of an upright-pillar guide member 35 and an upright-pillar inner member 36. The upright-pillar guide member 35 is formed into a substantially U-shape in cross section which is open toward the front of the vehicle, and is provided with an outer surface portion 35 a which faces toward the outside of the vehicle, an inner surface portion 35 b which faces toward the inside of the vehicle, and a connecting portion 35 c which connects the outer surface portion 35 a and the inner surface portion 35 b. The upright-pillar inner member 36 is provided with an outer surface portion 36 a which extends substantially parallel to the outer surface portion 35 a of the upright-pillar guide member 35, an inwardly projecting portion 36 b which is formed to project toward the inside of the vehicle to be positioned close to the center pillar 51, and a connecting portion 36 c which connects the outer surface portion 36 a and the inwardly projecting portion 36 b. The upright-pillar guide member 35 and the upright-pillar inner member 36 are fixed to each other by spot welding at positions 59 (front end portions of the inner surface portion 35 b and the inwardly projecting portion 36 b, and the connecting portions 35 c and 36 c) shown in FIG. 3.

In the side sash 13, the area surrounded by the outer surface portion 35 a, the inner surface portion 35 b and the connecting portion 35 c forms a glass-run retaining part (retaining groove) 30. A glass run 55 for elastically holding the rear edge of the window pane 58 is fitted into the glass-run retaining part 30 to be retained thereby. In addition, the area surrounded by the inner surface portion 35 b of the upright-pillar guide portion 35 and the inwardly projecting portion 36 b of the upright-pillar inner member 36 defines a main frame portion 31 having a polygonal-tubular (sac-shaped) hollow sectional shape in the side sash 13. A weather strip 56 (hollow sealing portion) is fixed to the inwardly projecting portion 36 b, which serves as an element of the main frame portion 31, via a clip 57. When the door 10 is closed, the weather strip comes into contact with the center pillar 51 and is elastically deformed thereby, thereby preventing water droplets from entering the inside of the vehicle. In addition, the outer surface portion 35 a of the upright-pillar guide member 35 and the outer surface portion 36 a of the upright-pillar inner member 36 form a designed portion 32 in the side sash 13. A garnish 38 (shown by imaginary lines in FIG. 3) is mounted to an outer side of the designed portion 32.

The structure of a joint C (see FIG. 1) between the upper sash 12 and the side sash 13 will be hereinafter discussed with reference to the drawings from FIG. 4 onwards. A portion of the upper sash 12 in the vicinity of the joint C is elongated substantially linearly in the forward/rearward direction of the vehicle. The upper sash 12 is a molded product made of metal by roll forming and basically has an uniform cross-sectional shape in the aforementioned linearly elongated portion. However, only in an end part (rear end part) of the upper sash 12, the connecting arm portion 23 and the main frame portion 24 are cut off so that only the designed portion 22, which includes the glass-run retaining part 20 and the weather strip retaining part 21, remain intact (see FIGS. 5 and 9). Namely, at the rear end part of the upper sash 12, the main frame portion 24 and the connecting arm portion 23 are formed shorter than both the designed portion 22, and the glass-run retaining part 20 and the weather strip retaining part 21 that are positioned behind the designed portion 22. This end part of the main frame portion 24 that is formed short in length is formed as a sectional-shape-reduced portion 25 which is smaller in sectional shape (sizes in the vertical direction and the direction of the thickness of the vehicle door) than a main body of the main frame portion 24 that is positioned closer to the front of the vehicle than the end part of the main frame portion 24. Specifically, the sectional shape of the sectional-shape-reduced portion 25 has been reduced by crushing a side of the main frame 24 toward the designed portion 22 by a slight amount (see FIG. 8).

The upright-pillar inner member 36 of the side sash 13 is press-formed so that the width thereof gradually decreases upwardly, toward the joint C between the upper sash 12 and the side sash 13, from the downside of the upright-pillar inner member 36 that is positioned on the door panel 11 side. The upright-pillar inner member 36 is provided at the upper end thereof with an upper inclined surface portion 36 d which is formed to be continuous with the outer surface portion 36 a and to be inclined toward the inside of the vehicle while extending upwardly, and is provided at the upper end of the upper inclined surface portion 36 d with an upper-edge end portion 36 e formed by bending. The upright-pillar inner member 36 is further provided at the upper end thereof with an arc-shaped bent portion 36 f which is curved toward the front of the vehicle while extending upwardly, and a superposed contact portion 36 g is formed at the end of the arc-shaped bent portion 36 f. The superposed contact portion 36 g has a cup-shaped (U-shaped) cross sectional shape which is open toward the outside of the vehicle so that the inner surface of the superposed contact portion 36 g can be laid over the outer surfaces of the sectional-shape-reduced portion 25 and the connecting arm portion 23 as shown in FIG. 8. In FIGS. 4 and 5 that show a state viewed from the outside of the vehicle, the outer surface (convex surface) of this cup-shaped superposed contact portion 36 g is shown. The range of formation of the upright-pillar guide member 35 along the upright-pillar inner member 36 extends only to a position below the arc-shaped bent portion 36 f, so that the superposed contact portion 36 g is in an exposed state, with the opening thereof that faces toward the outside of the vehicle not being closed by the upright-pillar guide member 35. Accordingly, the superposed contact portion 36 g and the sectional-shape-reduced portion 25 can be superposed on each other in the direction of the thickness of the vehicle door as shown in FIG. 8.

When joined together, the upper sash 12 and the side sash 13 are combined so that the sectional-shape-reduced portion 25 is fitted into the superposed contact portion 36 g as shown in FIG. 8. FIGS. 4 and 6 show a state where the sectional-shape-reduced portion 25 is fitted into the superposed contact portion 36 g. In this fitted state, an inner surface of the superposed contact portion 36 g is fitted on outer surfaces of the sectional-shape-reduced portion 25 and the connecting arm portion 23 to thereby prevent the superposed contact portion 36 g from deviating toward the front area of the main frame portion 24. Thereafter, the upper sash 12 and the side sash 13 are joined together by welding together the superposed portions between the sectional-shape-reduced portion 25 and the superposed contact portion 36 g. According to this joint structure, the sectional-shape-reduced portion 25 and the superposed contact portion 36 g that are superposed on each other in the direction of the thickness of the door 10 constitute a joint between the upper sash 12 and the side sash 13. Accordingly, as compared with a type of joint structure in which end surfaces of an upper sash member and an upright-pillar sash member are butt-joined to each other, no strict accuracy control for this joint is necessary, the joining operation is easy, and has excellent productivity characteristics. Moreover, the joint structure is superior in strength because a large joining area can be secured.

On the vehicle rear side behind the superposed area between the sectional-shape-reduced portion 25 and the superposed contact portion 36 g, the upper sash 12 does not interfere with the arc-shaped bent portion 36 f of the side sash 13 that lies on a line extended from the main frame portion 24 because the main frame portion 24 and the connecting arm portion 23 of the upper sash 12 are removed therefrom. On the other hand, there is no weld seen on the outer surface of the designed portion 22 between the designed portion 22 and the side sash 13 since the designed portion 22 of the upper sash 12 is continuously formed in the rear end part of the upper sash 12, in which the main frame portion 24 is cut off, and since the upper-edge end portion 36 e of the side sash 13 is formed so as to be in contact with an inner surface of the glass-run retaining part 20 at a position offset toward the inside of the vehicle away from the designed portion 22. Accordingly, a process for making welded marks inconspicuous is no longer necessary, which also contributes to an improvement in productivity.

FIGS. 11 through 14 show a different embodiment from the first embodiment. The previous embodiment shown in FIGS. 1 through 10 has a superposed relationship between the upper sash 12 and the side sash 13, in which the sectional-shape-reduced portion 25 that is smaller in sectional shape than a main body of the main frame portion 24 is formed at an end part of the main frame portion 24 of the upper sash 12 and the superposed contact portion 36 g of the side sash 13 covers an outer surface of the sectional-shape-reduced portion 25. In contrast to this, in the present embodiment, no process for reducing cross-sectional size is performed on the end part of the main frame portion 24 of the upper sash 12; instead, a superposed contact insertion portion 36 h which is smaller in cross sectional shape than the superposed contact portion 36 g of the previous embodiment is formed at an end of the arc-shaped bent portion 36 f. More specifically, the superposed contact insertion portion 36 h is inserted into the inside of the main frame portion 24 that has a polygonal-tubular hollow sectional shape, and is formed to have a shrunk shape in cross section so that the outer surface of the superposed contact insertion portion 36 h contacts an inner surface of the main frame portion 24. The superposed contact insertion portion 36 h has a U-shaped cross sectional shape which is open toward the outside of the vehicle, and the inner surface (concave surface) of this U-shaped superposed contact insertion portion 36 h is shown in FIG. 12 (and FIG. 11) that illustrates a view from the outside of the vehicle. Aside from the superposed contact insertion portion 36 h, the arc-shaped bent portion 36 f is further provided at the end portion thereof with an extension retaining portion 36 i which is formed to extend straight forward with no stepped portion given to the arc-shaped bent portion 36 f.

When the upper sash 12 and the side sash 13 are combined, the superposed contact insertion portion 36 h of the side sash 13 is inserted inside the hollow main frame portion 24, which causes the outer surface of the superposed contact insertion portion 36 h and an inner surface of the main frame portion 24 to be overlaid on each other as shown in FIG. 14. Simultaneously, the extension retaining portion 36 i is not inserted into the main frame portion 24, but is placed on an outer surface (surface on the inside of the vehicle) of the connecting arm portion 23 of the upper sash 12. Namely, the main frame portion 36 h and the extension retaining portion 36 i sandwich the main frame portion 24 and the extension retaining portion 36 i from inside and outside, respectively. Thereupon, the superposed contact portions of these elements are fixed together by welding, or the like, to combine the upper sash 12 and the side sash 13. In this construction also, no strict accuracy control for the joint is necessary while productivity is excellent since each of the main frame portion 36 h and the extension retaining portion 36 i is overlaid on the main frame portion 24 in the direction of the thickness of the door 1; moreover, the large joining area makes it advantageous to secure strength.

As described above, the door frame structure according to the present invention makes it possible to join the upper sash 12 and the side sash 13 to each other easily and securely and obtain high productivity. However, the present invention is not limited to the above illustrated embodiments, and modifications and variations of the invention can be made without departing from the spirit and scope of the invention. For instance, in the above illustrated embodiments, the arc-shaped bent portion 36 f is formed to be continuous with the upper end of the inwardly projecting portion 36 b in the upright-pillar inner member 36, and the end of the arc-shaped bent portion 36 f is formed as the superposed contact portion 36 g, or the superposed contact insertion portion 36 h (and the extension retaining portion 36 i), which is a portion to be joined to the upper sash 12. Although this structure has the merit of the door frame being able to be manufactured in a relatively easy manner with no need to increase the number of elements, a joint corresponding to the superposed contact insertion portion 36 h, or the superposed contact insertion portion 36 h and the extension retaining portion 36 i, can be formed with no involvement of a bent portion such as the arc-shaped bent portion 36 f.
